Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a breathing exercise device for postoperative rehabilitation in cardiology. Background Technology

[0002] Breathing exercise devices play an important role in postoperative rehabilitation in cardiology, helping patients recover their health and improve their quality of life by strengthening respiratory muscles, improving lung function, preventing complications, promoting gas exchange, and relieving anxiety.

[0003] However, existing breathing trainers have some hygiene and cleaning issues during use. For example, after use, the mouthpiece may be contaminated with dirt, bacteria or other contaminants. If it is not cleaned and disinfected in time, users may come into contact with the contaminated mouthpiece the next time they use it, increasing the risk of infection and cross-infection.

[0004] Meanwhile, the air inlet of the upper blowing valve of existing breathing trainers is easily damaged by dust, impurities and other contaminants, which can lead to blockage or damage, thus affecting the overall service life of the breathing trainer. In addition, during the use of the breathing trainer, the exhaled air is cooled as it passes through the breathing trainer, causing water vapor in the air to condense into water droplets. This is because the temperature and humidity inside the breathing trainer are different from the environment, resulting in a large amount of water vapor being generated inside the breathing nozzle of the breathing trainer, which makes it easier for bacteria to grow and for odors to be generated, thus affecting the hygiene standards of the training equipment.

[0005] Therefore, a breathing exercise device for postoperative rehabilitation in cardiology was proposed to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a breathing exercise device for postoperative rehabilitation in cardiology, comprising: a support base and three flow cylinders fixedly mounted laterally at equal intervals on the surface of the support base. Each flow cylinder contains an indicator ball. A cylinder-mounted downward blowing valve is also provided on one side of the surface of the support base. The upper ends of the flow cylinders and the cylinder-mounted downward blowing valves are fixedly connected to a gas exchange chamber, and both the flow cylinders and the cylinder-mounted downward blowing valves are connected to the gas exchange chamber.

[0008] Preferably, the two bundle plates are grouped together, and the two bundle plates together form an elastic constraint buckle, and the middle part of the medical corrugated tube is constrained and placed in the adapter groove by the bundle plates.

[0009] Preferably, the support plate is an arc shape that conforms to the human chin, and the surface is provided with a soft padding layer.

[0010] Preferably, the cleaning head initially covers the periphery of the mouthpiece, and the interior of the cleaning head is movably bonded with a disinfecting sponge layer adapted to the diameter of the mouthpiece, and the disinfecting sponge layer inside the cleaning head can be quickly replaced.

[0011] Preferably, the leak-proof dehumidification mechanism includes a plate fixing ring fixedly connected to the circumferential surface of the lower air valve of the belt cylinder. A torsion spring shaft is rotatably connected to the surface of the plate fixing ring. A winding shaft is fixedly connected to the top end of the torsion spring shaft. A pull rope is wound around the circumferential surface of the winding shaft. A fixing shaft is fixedly connected to the lower end of the auxiliary plate near the plate fixing ring. The end of the pull rope away from the winding shaft is fixedly connected to the fixing shaft. A fan-shaped toothed plate is fixedly connected to the top end of the winding shaft. A toothed slide plate is engaged with the toothed end of the fan-shaped toothed plate. A limiting groove is fixedly connected to the plate fixing ring near the toothed slide plate. The toothed slide plate is slidably connected to the limiting groove. A push ring is fixedly connected to the top end of the toothed slide plate via a connecting rod.

In its initial state, the push ring is located in front of the air inlet and does not contact the connection port of the medical corrugated tube. Furthermore, the inner diameter of the push ring is compatible with the outer diameter of the medical corrugated tube interface.

[0014] Preferably, the top cover covers the upper air valve, and the front end of the top cover has a notch. The top cover is not blocked by the bottom baffle when it is flipped. A dehumidifying bag is movably attached to the top of the inside of the top cover. The dehumidifying bag contains activated carbon particles and can be quickly replaced.

[0015] Compared with the prior art, the present invention provides a breathing exercise device for postoperative rehabilitation in cardiology, which has the following beneficial effects:

[0016] 1. The retaining ring design allows the medical corrugated tube to be installed at the air inlet in a naturally curved and contracted state. Furthermore, the binding plate ensures the medical corrugated tube is neatly constrained within the fitting groove, preventing it from tangling or being twisted or damaged by external pressure during use. This not only guarantees unobstructed airflow during use but also avoids the risk of ineffective respiratory training due to damaged or blocked medical corrugated tubes. Simultaneously, the binding plate automatically pulls and extends the medical corrugated tube to meet the user's needs, thus reducing the number of steps required for operation.

[0017] 2. The height of the support board can be adjusted by the telescopic plate, keeping it parallel to the chin and preventing the body from bending or leaning forward, which could lead to breathing difficulties. It also allows users of different body types to maintain an upright airway during rehabilitation training, thus keeping the airway clear, ensuring proper exertion of respiratory muscles, and providing good respiratory control and efficiency. This not only reduces the burden on other parts of the body but also improves the effectiveness of rehabilitation training.

[0018] 3. When not in use, the cleaning head covers the outer surface of the mouthpiece to protect it, preventing the cleaned mouthpiece from being exposed to dust and impurities. Furthermore, during the pre-use preparation of the breathing trainer by flipping the auxiliary plate, the cleaning head automatically wipes and cleans the mouthpiece, preventing the user from forgetting or failing to clean it in time, thus improving the hygiene standards of breathing trainer use and reducing the risk of infection and cross-infection.

[0019] 4. During use, the push ring automatically pushes the medical bellows to ensure that the connection between the medical bellows and the air inlet is tightened before each use. This prevents the connection from becoming loose or insecure, ensuring smooth airflow and helping the breathing trainer to work properly, providing accurate and reliable breathing resistance or flow. At the same time, when the breathing trainer is in use, the push ring will continuously press against the connection between the medical bellows and the air inlet, thus preventing the medical bellows from falling off the air inlet due to user movement or accidental contact. This reduces the possibility of accidental interruption of breathing training and provides a continuous and stable breathing training environment.

[0020] 5. The top cover protects the air inlet of the upper air valve from dust, effectively preventing dust, impurities, and other pollutants from entering the air inlet. This avoids blockage or damage caused by dust and impurities, thus extending the overall lifespan of the breathing trainer. Furthermore, a dehumidifying bag is attached to the top of the inside of the top cover. When the user replaces the top cover with the upper air valve, the dehumidifying bag absorbs any moisture from the air exchange chamber, flow cylinder, and lower air valve, keeping them dry and reducing bacteria and odors, resulting in a cleaner and more comfortable training device.

All air valves 103 are connected to the gas exchange chamber 104. An upper air valve 105 is fixedly installed on the upper end of the gas exchange chamber 104 near the flow cylinder 101. An air inlet 106 is opened on the side of the gas exchange chamber 104 near the lower air valve 103. A medical corrugated tube 107 is inserted into the outer circumferential surface of the air inlet 106. A mouthpiece 108 is inserted into the end of the medical corrugated tube 107 away from the air inlet 106. A self-cleaning adaptation mechanism and a leak-proof dehumidification mechanism are respectively provided on the side of the gas exchange chamber 104 near the lower air valve 103.

[0033] The self-cleaning adaptation mechanism includes an auxiliary plate 201 rotatably connected to the surface of the support base 1 near the lower air valve 103 of the tube. An adapter groove 202 is provided on the upper end of the auxiliary plate 201 near the gas exchange chamber 104. A bundle plate 203 is symmetrically fixed to one side of the auxiliary plate 201 around the adapter groove 202. A telescopic plate 204 is fixedly connected to one end of the auxiliary plate 201. An auxiliary support plate 205 is fixedly connected to the end of the telescopic plate 204 away from the auxiliary support plate 205. A suction cup 206 is fixedly installed at the bottom of the telescopic plate 204. A retaining ring 207, made of elastic plastic, is fixedly connected to the top of the gas exchange chamber 104 near the lower air valve 103. A bite nozzle 108 is engaged and placed inside the retaining ring 207. A fixing rod 208 is fixedly connected to the top of the gas exchange chamber 104 near the lower air valve 103. A sliding groove 209 is fixedly connected to the top of the fixing rod 208. A rod-mounted groove body 210 is slidably connected inside the body 209. A torsion spring shaft 211 is rotatably connected to the side of the groove body 209 away from the fixed rod 208. A winding shaft 212 is fixedly connected to the end of the torsion spring shaft 211 away from the telescopic plate 204. A pull rope 213 is wound around the circumference of the winding shaft 212. A fixed shaft 214 is fixedly connected to the side of the auxiliary plate 201 away from the flow cylinder 101. The pull rope 213 is located away from the winding shaft 212. One end is fixedly connected to the fixed shaft 214. The top surface of the winding shaft 212 is eccentrically fixedly connected to the crank rod 215. The end of the crank rod 215 away from the winding shaft 212 is fixedly connected to the slider 216. The slider 216 is slidably connected in the rod groove 210. The side of the rod groove 210 away from the slide groove 209 is fixedly connected to the turning rod 217. The end of the turning rod 217 away from the rod groove 210 is fixedly connected to the cleaning head 218.

[0034] Among them: two bundle plates 203 form a group, and the two bundle plates 203 together constitute an elastic constraint buckle. The middle part of the medical corrugated tube 107 is constrained and placed in the adapter groove 202 by the bundle plates 203.

[0035] The support plate 205 is curved to fit the human chin and has a soft padding layer on its surface;

[0036] The stretchable length of the pull cord 213 is exactly the length of the auxiliary plate 201 that drives the fixed shaft 214 to rotate. When the pull cord 213 is fully stretched, it will drive the cleaning head 218 to be located directly in front of the mouthpiece 108.

[0037] In its initial state, the cleaning head 218 covers the periphery of the mouthpiece 108, and the interior of the cleaning head 218 is fitted with a sterilizing sponge layer that is adapted to the diameter of the mouthpiece 108. The sterilizing sponge layer inside the cleaning head 218 can be quickly replaced.

[0038] Further examples: Please refer to Figures 9 to 10 As shown:

[0039] The leak-proof dehumidification mechanism includes a plate fixing ring 301 fixedly connected to the circumferential surface of the air blowing valve 103 under the belt cylinder. A torsion spring shaft 302 is rotatably connected to the surface of the plate fixing ring 301. A winding shaft 303 is fixedly connected to the top of the torsion spring shaft 302. A pull rope 304 is wound around the circumferential surface of the winding shaft 303. A fixing shaft 305 is fixedly connected to the lower end of the auxiliary plate 201 near the plate fixing ring 301. The end of the pull rope 304 away from the winding shaft 303 is fixedly connected to... On the fixed shaft 2 305, the top end of the winding shaft 2 303 is fixedly connected to a fan-shaped toothed plate 306. The toothed end of the fan-shaped toothed plate 306 is engaged with a toothed slide plate 307. The plate fixing ring 301 is fixedly connected to a limiting groove 308 near the toothed slide plate 307. The toothed slide plate 307 is slidably connected in the limiting groove 308. The top end of the toothed slide plate 307 is fixedly connected to a push ring 309 through a connecting rod. The side of the telescopic plate 204 near the upper air valve 105 is fixedly connected to a top cover 310 through a connecting rod.

[0040] Among them: the suction force of suction cup 206 is greater than the torsional force of torsion spring shaft 1 211 and torsion spring shaft 2 302, and the torsional force of torsion spring shaft 1 211 and torsion spring shaft 2 302 is greater than the self-weight of auxiliary plate 201, telescopic plate 204 and auxiliary support plate 205.

[0041] The stretchable length of the pull rope 2 304 is exactly the length at which the push ring 309 fully contacts the connection port of the medical corrugated tube 107.

[0042] The push ring 309 is made of elastic plastic. In its initial state, the push ring 309 is located in front of the air inlet 106 and does not contact the connection port of the medical bellows 107. Furthermore, the inner diameter of the push ring 309 is compatible with the outer diameter of the interface of the medical bellows 107.

[0043] The top cover 310 covers the upper air valve 105, and the front end of the top cover 310 is provided with a notch. When the top cover 310 is flipped, it will not be blocked by the bottom baffle. A dehumidifying bag is movably glued to the top of the inside of the top cover 310. The dehumidifying bag is filled with activated carbon particles, and the dehumidifying bag inside the top cover 310 can be quickly replaced.

[0044] The working principle of all the content in the above embodiments is as follows:

[0045] In the initial state: the auxiliary plate 201 and the telescopic plate 204 did not rotate 90 degrees, the telescopic plate 204 did not drive the auxiliary support plate 205 to extend or retract, the suction cup 206 was not attached to the table, the torsion spring shaft 1 211 and the torsion spring shaft 2 302 were not subjected to tension and rotated, the cleaning head 218 did not clean back and forth on the mouthpiece 108, and the push ring 309 did not contact the medical corrugated tube 107.

[0046] The following is the working process of the self-cleaning adaptation mechanism:

[0047] In use, the user first places the support base 1 horizontally on a table level with the user's chest. Then, one end of the medical corrugated tube 107 is connected to the mouthpiece 108, and the other end is connected to the air inlet 106. The middle section of the medical corrugated tube 107 in its contracted state is then secured in the adapter slot 202 via the clamping plate 203. Next, the mouthpiece 108 is horizontally secured in the retaining ring 207 along the extension direction of the medical corrugated tube 107. This is the initial placement and installation process of the breathing trainer. After this process, the user can rotate the auxiliary plate 201 ninety degrees away from the gas exchange chamber 104, allowing the suction cup 206 to adhere and fix to the table. The telescopic plate 204 and the support plate 205 are kept vertically fixed. Then, the user can keep their head parallel to the vertical direction of the breathing training. Then, according to the user's different body shape, the height of the telescopic plate 204 is adjusted upward so that the support plate 205 touches the chin. Then, the adjustment is stopped and the support plate 205 supports the chin. At the same time, the auxiliary plate 201 rotates downward ninety degrees, which will drive the middle part of the medical corrugated tube 107 to move downward through the binding plate 203. Since one end of the medical corrugated tube 107 is locked and fixed in the retaining ring 207 by the bite 108, the medical corrugated tube 107 will automatically extend during the downward movement of the binding plate 203.

[0048] Therefore, by setting the retaining ring 207, the medical corrugated tube 107 is installed at the air inlet 106 in a naturally bent and contracted state. Furthermore, by setting the binding plate 203, the medical corrugated tube 107 is neatly constrained within the adapter groove 202, thereby preventing the medical corrugated tube 107 from tangling or being twisted and damaged by external pressure during use. This not only ensures the smooth flow of gas during use but also avoids the risk of the respiratory training device being ineffective due to damage or blockage of the medical corrugated tube 107. At the same time, the binding plate 203 automatically pulls and extends the medical corrugated tube 107 to increase its length to meet the user's needs, thereby reducing the user's operating steps.

[0049] Furthermore, the height of the support plate 205 can be adjusted by the telescopic plate 204, so that the support plate 205 keeps the chin parallel to the body, thereby avoiding the body bending or leaning forward, which would cause breathing difficulties. At the same time, it meets the needs of users of different body types to keep the airway upright during rehabilitation training, thereby keeping the airway open, ensuring the correct exertion of respiratory muscles, and thus providing good breathing control and efficiency. This not only reduces the burden on other parts of the body, but also improves the effect of rehabilitation training.

[0050] Furthermore, since the auxiliary plate 201 rotates downwards by ninety degrees, it will cause the fixed shaft 214 to move downwards in an arc around the rotation point of the auxiliary plate 201. This will cause the fixed shaft 214 to pull the rope 213, causing the winding shaft 212 and the torsion spring shaft 211 to rotate clockwise. At this time, the torsion spring shaft 211 will be deformed by torsional force. The crank 215 will rotate synchronously with the winding shaft 212, causing the slider 216 to slide up and down in the groove of the rod groove 210, thereby causing the rod groove 210 to move. 10 moves back and forth within the chute 209, eventually driving the cleaning head 218 to wipe the inner and outer surfaces of the mouthpiece 108 repeatedly until the auxiliary plate 201 remains horizontally fixed. At this point, the pull rope 213 is fully stretched, so the cleaning head 218 will stop wiping and moving. At this point, the cleaning head 218 is located directly in front of the mouthpiece 108 and will not obstruct it vertically, so that the user can remove the mouthpiece 108 from the retaining ring 207 for breathing exercises.

[0051] Therefore, the cleaning head 218 protects the outer surface of the mouthpiece 108 when not in use, preventing the cleaned mouthpiece 108 from being exposed to dust and impurities. Furthermore, during the pre-preparation process of the breathing trainer by flipping the auxiliary plate 201, the cleaning head 218 automatically wipes and cleans the mouthpiece 108. This prevents the user's mouth from coming into contact with contaminated mouthpiece 108 due to the user forgetting or failing to clean it in time, thereby helping to improve the hygiene standards of using the breathing trainer and reducing the risk of infection and cross-infection.

[0052] Please refer to the above work process. Figures 1 to 9 .

[0053] The following is the working process of the leak-proof dehumidification mechanism:

[0054] In use, the auxiliary plate 201 rotates downwards at a 90-degree angle, causing the fixed shaft 305 to move downwards in an arc around the rotation point of the auxiliary plate 201. This, in turn, pulls the pull rope 304 via the fixed shaft 305, causing the torsion spring shaft 302 and the winding shaft 303 to rotate clockwise. At this time, the torsion spring shaft 302 is deformed by the torsional force. The clockwise rotation of the winding shaft 303 causes the sector toothed plate 306 to rotate synchronously, thereby pushing the meshing toothed slide plate 307. The limiting groove 308 slides to the right, thereby driving the push ring 309 to move synchronously. The push ring 309 pushes the connection between the medical corrugated tube 107 and the air inlet 106 to ensure that the medical corrugated tube 107 and the air inlet 106 are tightly connected. When the auxiliary plate 201 is flipped and kept in a horizontal state, the second pull rope 304 is in a fully stretched state, and at this time the push ring 309 pushes the connector of the medical corrugated tube 107 to tightly contact the air inlet 106.

[0055] Therefore, during the use of the breathing trainer, the push ring 309 automatically pushes the medical bellows 107 to ensure that the connection between the medical bellows 107 and the air inlet 106 is tightened before each use, thereby preventing the connection from becoming loose or unstable and ensuring that the airflow can pass smoothly. This helps to ensure that the breathing trainer can work normally and provide accurate and reliable breathing resistance or flow. At the same time, when the breathing trainer is in use, the push ring 309 will continuously press against the connection between the medical bellows 107 and the air inlet 106, thereby preventing the medical bellows 107 from falling off the air inlet 106 due to user movement or accidental touch, thus reducing the occurrence of accidental interruption of breathing training and providing a continuous and stable breathing training environment.

[0056] Furthermore, the flipping of the telescopic plate 204 simultaneously flips the top cover 310, thus removing the cover from the upper air inlet valve 105. Users can adjust the resistance of the upper air inlet valve 105 according to training needs. Therefore, when the breathing trainer is not in use, the top cover 310 effectively prevents dust, impurities, and other contaminants from entering the air inlet of the upper air inlet valve 105, thus avoiding blockage or damage and extending the overall lifespan of the breathing trainer. The top cover 310 has a long service life, and a dehumidifying bag is attached to the top of the inside. When the user finishes using the equipment and covers the top cover 310 back onto the surface of the upper air valve 105, the dehumidifying bag inside the top cover 310 will absorb the breathing moisture present in the gas exchange chamber 104, the flow cylinder 101, and the lower air valve 103 after use. This keeps the inside of the gas exchange chamber 104, the flow cylinder 101, and the lower air valve 103 dry, which helps reduce the generation of bacteria and odors, thus providing a cleaner and more comfortable training equipment.

[0057] In addition, after using the breathing trainer, the suction cup 206 can be lifted by pulling the edge of the suction cup 206 so that the suction cup 206 is no longer attached to the table. At this time, the torsional force of the torsion spring shaft 211 and the torsion spring shaft 302 will pull the above-mentioned moving parts to move in the opposite direction and reset.

[0058] Please refer to the above work process. Figures 9 to 10 .
